Davis Wiki is a really great local wiki that focuses entirely on the city of Davis, California. Some of the features that make it unique are an interactive map, which provides another way to navigate the wiki! I gotta figure out how they did that. You can drill down on the map easily get to any store, business or other attraction for which there is a wiki article, here's an example of an article. A look at the RecentChanges page shows that the wiki is clearly vibrant and what else is neat is that there seem to be 500 or so people with personal pages. UC Davis is right there and that probably works to the wiki's advantage in that students dig interactive web sites like Facebook, etc. and the wiki is even easier to use.

There are a number of "citi-wikis", like the BerlinWiki (Wikia) for example, but Davis Wiki stands out because it has really captured the hearts and minds of its community. What is the secret? I hope to see more like this!
